I have seen a few posts recommending mod_proxy_http a little bit over  
mod_jk. Why is that?

I used mod_jk recently simply because it was on the tomcat site. I  
just assumed it was the default/best option. Maybe there should be a  
link on http://tomcat.apache.org/download-connectors.cgi indicating  
that you might want to look at mod_proxy_http saying something like it  
might meet your needs better.

best,
-Rob

Note that mod_jk and mod_proxy_ajp fill the same role: they use the AJP
protocol to connect Apache httpd to Tomcat (or any AJP-compliant
application server). mod_proxy_http does the same thing, but uses the
HTTP protocol, and so has a few options missing (not exactly sure what
they are).

I chose mod_jk over mod_proxy_ajp for two reasons:

1. mod_jk has been around for years, and it was the only game in town
   when I got started.

2. I find that mod_jk is more configurable for complex deployments.
   I tried to switch to mod_proxy_ajp when we moved to Apache httpd
   2.2.x, but I had a hard time getting it to do what I wanted it
   to do, so I stuck with mod_jk.

Filip didn't explain his recommendation, but I believe Filip was
suggesting that mod_proxy_http was more robust than mod_proxy_ajp and
might not have the same problems. From my experience, mod_jk is very
robust and reliable.

Hope that helps,
